To all whom it may concern:

Be it known that i, VVILLIAM- it. PARK, of Taunton, in the county of Bristol, and in the btate of Massachusetts, have invented certain new and useful improvements in Mechanical Movements; and i do hereby declare that the following is a full, clear, and exnctdescripticn thereof, reference being had to the accompanying drawings, melting a part of thi' speciflcar tion in which- 4 1 Figure 1 shows ivi'iew of my invention in elevation. Fig. 2 shows adetaii view of the sliding tappet and pin-plate, with the tnppet shown in position as at the limit of its movement in one direction; Fig. 3, oi-similar view with the lapoet shown as just striking one of the pins on its return movement from the no: sitio'ii shown in Fig. 2, and Fig, 4 a ill-Z8 view with the tappet shown in position at the limit of its movement opposite to that shown in Fig.

Letters of like name nnd kind rel'er parts in each of the figures.

The object o! my invention is to provide an improved means for converting rectilinear reciprocating into rotary motion; and to this end it consists in the combination of n face-plate or dish provided with pins projecting from one face thereof with a reciprocating tappet with its ends cuoon an incline and adopted to engage said pins, snbstantinily as hereinnlte. described, and specifically set forth in the claims.

In the drawings, A designates the face-plate or dish,'heving a. series of pins equidistant from each other set in one face thereof, and in c circle concentric with the disk. These pins must be odd in number, so that no one oi' them can he diametrically opposite another. The number is of course to depend upon the distance through which it is desired that the dish shonhl turn at each reciprocation of the topto like not 4.). The ends of this tcppet are cut away,

as showinon lines at an angle with the lcngi tndinoi edges of the tnppetpiate and parallel with each other. iihese ends therefore present inclined henringenrinces for engagement with thepinn on the disk as the tnppct reciprocation,

and said disk ohviousiy will he turned in the some direction each time that either endot ihe tappet engages with e pin. The width of desired.

the tappet is nearly equal to the distance between two adjacent pins, and its length is such that when one end comes into contact with a pin the other end shall leave contact with the pin on the opposite edgcof the disk. This disk is attached to a shaft, I), which is jour- & collar and set-screw. The tappet is fastened nailed in thehridgc F nnd held in posit-io'nby v by screws up therwise to at bar, F, which slides in hearings in the upright supports hill of the bridge-piece E. Pins G near the ends of the no i. serve to limit its motion by striking against the hearings. Separate guiding and hearing pieces can of course be provided, if 6 As the tnppet is of snchn length that one end does notpass out ofengagement. with a pin on the disk until the other end comes into engagement with another pin, itis obvious that theiilislt will be positively tnrned 7 hr, tillii cannot be turned to any extent in either direction without, the action of the tappeh Said t'appet, then, while intermittingly serving to turn the disk in one direction, also serves to lock the sameagainsfiany independout movement.

Such a, mechanical movement 1 is of use wherever it is desired to convert rectilinear reciprocntingi'nto rotaryinotion. ltcan be used to great advantage to turn the calendar cylin- Here or disks in calei'nlnr-cloclts, and the registeringm'heeis in a, register for piston watermeters. in the calendar-clocks the pawl-rod is to be attached directly to the tappet-bnr F,

and in the ease of meters this bar is to be connected with the reciprocating piston or some port moving therewith,

The shaft D is to be geared in tiny snitnblc way with the re istering devices.

iiaving thus hilly set forth the nature and merits; of my invention, what I claim isl. The combination of the rotary disk provided with n series oi pins projecting from its i'ace, reciprocnting tnppct having both ends not on on inciinc tothe line of its reciprocn-' 5 ticn, end ndapted to engage with the pins andimport rotary motion to the disk in its reciprocation, and means for reciprocating" the tappet, substantially as and for the purpose set forth.

it. The combination of the disk having e series of pins equidistant from each other, or-

J artensen ranged concentric with the axis of rotation of its ends cut on an incline to the line of its reciprocation and parallel to each other, all so arranged that the tappet will turn the disk an equal distance in the same direction at each reciprocation.

The combination of the rotary disk, the series of pins, the tappet with parallel inclined ends, and the reciprocating bar, substantially as and for the purpose set forth.

4. The combination of the shaft 1), disk A, series of pins B B, tapp et (J, with parallel inclined ends, bar I pins G G, and bridge E,

with its supports 11 1], formed with bearings for bar F, substantially as and for the purpose described.

5. The combination of the reciprocating bar vided with a concentric series of equidistant pins, uneven in number, projecting froin'its face, and the double-acting reciprocating tappet, engaging said pins, and having a width nearly equal to the distance between two adjacent pins, and a length such that one end does not pass out of engagement with one pin until the opposite end goes into engagement with another, all so arranged that the tappet not only serves to turn the, disk, but looks the same against independent movement.

In testimony that I claim "the foregoing I have hereunto set my hand this 8th day of March, 1883. v
